Potted panel latch system

ABSTRACT

A method of preparing a finished panel and latch combination, wherein the panel and latch mounting combination are seamless and attractive.

TECHNICAL FIELD

This invention relates to a recessed latch system, and more particularly to a latch system which is fabricated in a fashion that creates a seamless appearance and complements or blends in with the supporting panel, greatly improving the appearance and sanitation.

BACKGROUND OF THE INVENTION

Latch members for securement for storage in passenger vehicles, including airplanes, have typically been recessed to avoid inadvertent snags or injuries. Typically, these latch members are pre-fabricated and simply secured into a pre-prepared opening in the panel. Although this is economical and functional, it yields a product which is utilitarian, unattractive and creates an environment difficult to clean.

Hardware for use in airplanes in particular needs to be reliable, lightweight and attractive. Because of the economics and environment, these devices must be quickly and easily sanitized.

SUMMARY OF THE INVENTION

With the above-noted background in mind, it is highly desirable to produce a recessed latch system wherein the latch appears to be an integral part of the supporting panel.

It is further desirable to provide a recessed latch system wherein the exposed body of the latch and the surface of the panel present a unitary appearance.

It is still further desirable that a recessed latch and panel be fabricated in a manner which is simple and economical, yielding an attractive, seamless product.

BEST MODE FOR CARRYING OUT THE INVENTION

As seen in FIG. 1, which is exploded to expose all parts of the inventive installation, there is a honeycomb panel 2, a latch body or base 4, a blank or potting cover 6, a decorative coating or sheet 8 and a latch mechanism 10. Also seen in this view is a latch guide 12 and securement screws 14.

Reference is now had to FIGS. 2, 3, 4 and 5, wherein a base 4 and latch guide 12 are potted into a honeycomb panel 2. FIG. 2 depicts a potting cover 6 attached to the base 4. As illustrated in FIG. 2, the base 4 includes interior side walls 44 that form a boundary around the base 4, with an upper flange 15 extending outwardly from an upper end of the base 4 and a lower flange 66 extending outwardly from a lower end of the base 4, creating a cavity 17 therebetween. The interior side walls 44 include a plurality of seams 19 that are generally positioned around corner portions of the base 4. The upper flange 15 includes a plurality of apertures 18, which allow adhesive to be applied therethrough, as illustrated in FIG. 5, and fill the cavity 17 so as to allow the adhesive to bond the base 4 to the honeycomb panel 2. FIG. 3 shows the base 4 with the potting cover 6 positioned to be placed into a prepared cavity or recess 20 of the honeycomb panel 2. The potting cover 6 includes a plurality of apertures 26 that are positioned at a perimeter of the potting cover 6 and substantially align with the plurality of apertures 18 of the base 4 so as to allow the adhesive to be applied therethrough. Further, as illustrated in FIG. 3, the latch guide 12 is positioned to be coupled to the honeycomb panel 2 by securing the latch guide 12 within a latch guide opening 22. The latch guide opening 22 extends through a side surface 24 of the honeycomb panel 2 and intersects the recess 20. FIG. 4 illustrates the base 4 with the potting cover 6 secured to the prepared cavity or recess 20 and the latch guide 12 secured into the latch guide opening 22 of the panel 2; then it is potted in place using an adhesive applicator tube 16, as shown in FIG. 5.

Reference is now had to FIG. 6, wherein the base 4 is in place and the decorative coating 8 is about to be placed over the secured base 4 for the panel 2 and vacuumed into the cavity 20, covering the base 4 and the panel 2, forming a seamless transition from the surface of the panel throughout the base 4, as best seen in FIG. 7. This results in an attractive, easily cleaned panel and latch member.

As seen in FIG. 8, the latch mechanism 10 then is in place in position and secured with the screws 14, inserted through the latch guide 12, resulting in a finished panel and latch combination as seen in FIG. 9, wherein the smooth transition and the panel throughout the latch base is seamless and attractive.

Although a preferred embodiment has been disclosed for purposes of illustration, it should be understood that various changes and modifications and substitutions could be made in the preferred embodiment without departing from the spirit of the invention, as defined by the claims which follow: 

1-2. (canceled)
 3. A method of fabricating a potted panel latch, the method comprising: removing material from a face of a panel to form a recess therein, the recess being sized and shaped to receive a latch body; securing a latch body within the recess; and coupling a decorative sheet to the face of the panel, the decorative sheet overlying the latch body and a portion of the panel to provide an appearance of a continuous panel.
 4. The method of claim 3 wherein securing the latch body within the recess comprises: inserting the latch body within the recess; and applying an adhesive through apertures positioned on a flange of the latch body, the latch body including a cavity formed around an interface between the latch body and the panel, the cavity being filled with the adhesive so as to bond the latch body to the panel.
 5. The method of claim 4, further comprising: securing a potting cover to the latch body and a portion of the panel; applying the adhesive through potting cover apertures, the potting cover apertures being located to align with the apertures of the latch body; and removing the potting cover after applying the adhesive.
 6. The method of claim 4, further comprising: removing material from a side surface of the panel to define a latch guide opening; and securing a latch guide through the latch guide opening.
 7. The method of claim 4, further comprising: coupling a latch mechanism to the panel, wherein the latch mechanism is positioned within the latch body.
 8. The method of claim 7 wherein coupling the latch mechanism comprises: inserting the latch mechanism within the latch body; inserting a latch guide through a latch guide opening formed through a side surface of the panel; and fastening the latch guide to the latch mechanism with screws.
 9. The method of claim 3 wherein coupling the decorative sheet includes applying a vacuum to draw the decorative sheet through the recess to provide an appearance of a continuous panel.
 10. A method to decorate a face of a panel, the method comprising: forming a recess in the face of the panel, the recess being configured to receive a latch body; securing a latch body within the recess; and decorating the face of the panel to provide an appearance of a continuous panel.
